Remote control
In case your fan includes a remote control, 2 batteries of the
number 7 must be incorporated in order to be able to use it. To do
this, remove the back cover, place the batteries in the correct
position and close it again.
When using the remote control, the remote control emitter (located
on the front of the remote control) must be aligned with the signal
reception window on the product body (located on the front of the
body). Avoid direct sunlight to the reception window, so as not to
affect the reception effect.
The remote control can normally be used at 5 meters distance from
the front of the product and within a range of 30 degrees.
Please hold the remote control securely to avoid impacts and falls.
If the device will not be used for some time, it is recommended to
remove the batteries from the remote control.
